Definitions

  • the present invention relates to an upper manhole with cover, comprising, placed on its upper end two concentric rings, a movable inner ring carrying the cover and resting on a fixed outer ring by means of the surfaces vertically pressing one on the 'other of two helical teeth allowing, by rotation of the inner ring, to move it in the vertical direction relative to the outer ring.
  • Such an upper manhole with cover is known from DE-U-1 922483.
  • the teeth of the two rings are arranged on a helical flange and the two teeth rise in the vertical direction. Therefore the movable part, the inner ring, must be blocked by additional means, especially in view of the solicitation of this upper part of look by heavy vehicles.
  • such teeth mounted on flanges may be soiled quickly, reducing the mesh and the power of adjustment.
  • CH-A-601 582 also describes an upper manhole with cover where the teeth rise in the vertical direction, requiring locking means.
  • This upper manhole is made of concrete, requiring expensive manufacturing.
  • to release and turn the movable ring it must be raised too high and the adjustable height is too small.
  • the object of the invention to propose an upper viewing part with a robust construction resistant to solicitation by vehicles, the surface of which can be adjusted in the vertical direction in an easy manner and the construction of which does not require no additional blocking means and is relatively simple and inexpensive to manufacture.
  • this object is achieved by the upper manhole of the aforementioned type and comprising the elements of the characterizing part of the main claim. This upper manhole can advantageously be supplemented by the technical characteristics of the dependent claims.
  • the outer ring 3 has at its upper part and its inner contour a cast iron circle 6, resting by a collar 7 on the upper surface 8 of the concrete ring 3.
  • This circle cast iron (see Figure 2) is anchored by spans 9 engaging in notches 10, formed in the concrete ring.
  • the circle 6 comprises, in a discontinuous manner and arranged in the form of a helix with several turns, separate teeth 11 (FIG. 4) of rectangular shape and extending in horizontal direction inwards.
  • the inner ring 4, movable comprises a helical flange 12 with several turns with teeth 13 of rectangular shape, extending vertically. The engagement of a vertically extending toothing in a horizontally extending toothing causes blocking of the movable inner ring against possible rotation.
  • the top of the inner ring 4 is formed as a collar 14, receiving the cover 5.
  • the lower edge 15 of the latter and the inner edge 16 of the top of the inner ring 4 are chamfered and to block the cover 5 against any rotation, the latter has six fixing lugs, engaging in corresponding notches not shown in the inner ring 4.
  • a seal 19 is placed between the cover and the inner ring.
  • the pitch of the propellers is chosen according to the amplitude of the desired elevation. This amplitude is preferably 60 mm for the height adjustment, which allows, with a thickness of the covering 20 of about 25 mm, to lift up to twice the inner ring 4, respectively the cover.
  • the number of teeth 11 and 13 per revolution is, in this example, sixty, which allows the very fine adjustment of the cover 5 at the upper surface of the coating 20.
  • the inner ring 4 includes, to make it easier handling thereof, four handling openings 21.
  • the inner ring 4 is introduced into the latter, the two teeth 11 and 13 mesh with each other.
  • the inner ring is released by lifting it and turned to the right or to the left depending on whether you wish to lower or raise the ring 4 and the cover 5.
  • Figure 7 shows a preferred execution tielle, all in cast iron.
  • the outer ring 33 includes, like the circle 6 according to Figure 1, the same separate teeth 11 of rectangular shape arranged discontinuously in the form of a helix with several turns and extending in horizontal direction inwards.
  • a seal 36 for example made of felt, is placed in a countersink 37 inside the outer ring 33.
  • the cover 35 is placed flush with the upper edge of the two rings and has an outer flange 38 which rests in a groove 39 inside the inner ring.
  • the cover 35 is fixed by ribs 40 and has operating openings 41 for the operating tool 42, indicated in dotted lines. Similar maneuvering holes are found in the outer flange 43 of the outer ring 33.
  • the inner ring 34 with the cover 35 in the raised position, drawn in dotted lines, demonstrates the course of the possible elevation, which corresponds in this example at 80 mm.
  • Figure 5 shows a variant of the teeth, where the teeth 22 of the circle 6 of the outer ring 3 or the outer ring 33 and the teeth 23 of the helical flange 12 of the inner ring 4 or 34 have a triangular profile. but are furthermore arranged in the same manner as those of FIG. 4.
  • the teeth 24 do not protrude, as in the previous alternative embodiments, horizontally from the circle 6 but belong to a flange 25, linked to the circle 6 of the outer ring 3.
  • the teeth 26 are arranged in the same manner as on the helical flange 12 of the inner ring 4 and have a trapezoidal profile.
